USB Heated Insoles with 3 Heat Levels for Winter Comfort

Reliable warmth for cold-weather work, travel and outdoor sports.

These USB Heated Shoe Insoles provide consistent, adjustable warmth to keep your feet comfortable in low temperatures. Constructed from soft, flexible material, each insole is designed to contour to the shape of your foot for a secure, comfortable fit inside most everyday footwear, work boots or sports shoes. A built-in micro heating chip distributes heat evenly across the insole surface, helping to reduce cold spots and maintain a stable temperature.

The insoles connect via a standard USB cable to a power bank, laptop, desktop or other USB power source, making them practical for use at home, in the office or on the move. Three selectable heat settings allow you to fine-tune the temperature to match changing conditions, from chilly offices to freezing outdoor environments. The insoles can be trimmed along the marked guide lines to fit your shoe size, and the heating layer is enclosed to allow gentle hand washing (USB connector must be kept dry and fully dried before reuse).
